| Method |
P.133 right column 6th paragraph: "The generation time was determined by the use of the formula g =
(0.3xt)/(loga-logb) where g is generation time in minutes and t is
the elapsed time in minutes (during exponential growth between 4 and
8 hr of incubation), a is S. aureus population after 8 hr and b is
population after 4 hr of incubation." |
| Comments |
P.133 right column bottom paragraph: "As shown in Table 1, S. aureus showed slowest growth in FPC (fish protein concentrate, 56 min generation time) as compared to SP (soy protein, 50 min) or yeast (29 mm). The faster rate of growth and attainment of a higher final S. aureus population in yeast may have been due to differences in these substrates relative to the availability of more readily utilizable nutrients such as free amino acids, peptides and vitamins or cofactors." On whole milk doubling time was 31 min. Note- range of 27-30 min on heart infusion broth medium given in table 2 in link |
